I watch PH pretty closely. It stays at 7.5 or 7.6. I believe TA is around 50, but I don't usually test it as long as the PH stays stable. The CC was 1.0 so I shocked with MPS about a week ago, but my wife had the same irritation reaction the next time she went in a few days later. She used...

I am using the BBB method and my last fill was about 3 months ago. I used dichlor initially to achieve ~30ppm CYA. I tested recently and found the CYA is less than 10ppm now. I remember seeing that CYA needs to be periodically added to maintain its level but forgot about it. My wife has been...

Thanks for all the great information Chem Geek. One more question. Some reported benefits of borates are silky feeling water and reduced skin and eye irritation. Based on what you have said, I understand boric acid in this application will not be an irritant, but how does it reduce irritation...

Thanks JamesW and Chem Geek for the responses. I will get some boric acid. I have some follow up questions. In addition to being a PH buffer, does pure boric acid have the same qualities of reducing skin and eye irritation as Borax or Gentle Spa? It seems counter intuitive that any of these...

I am considering adding borates to my hot tub using Borax. All of the instructions I have found say to use Muriatic Acid with the Borax to balance the PH. Is there any reason I can't use Dry Acid instead? I already have Dry Acid readily available as PH Down. The amounts of Muriatic Acid and...
